Perhaps you should try some spelling variations:
doanh hanh » doanh thanh, doanh doanh, doanh nhan
hien xanh » hien nhanh, chieu xanh, hien khanh
hien hanh » dieu hanh
doanh anh » doanh doanh, doanh thanh, doanh sang
cong cong » cong dong, trong cong, dung cong
cong manh » cong danh, duong manh, cong thanh
manh toan » thanh toan, anh tuan, tinh toan
toan cau » toan cao, toan ban, toan tap

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: hoc ((hien xanh) or (hien hanh)) - ((doanh hanh) OR (doanh anh)) cua cong cong manh toan cau~.
• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((hien xanh) OR (hien hanh)) - ((doanh hanh) OR (doanh anh)) cua cong cong manh toan cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((hien xanh) or (hien hanh)) - ((doanh hanh) OR (doanh anh)) cua cong cong manh toan cau*".
